Use function static for once initialization of flag registry.

This is a workaround for the MSVC debug constexpr initialization issue
in absl::once_flag.

Re-write flags config. It doesn't have to be written in the convoluted
way it currently is in the opensource-only code path.

Handle pthread_getschedparam() failure.

Log an error message if pthread_getschedparam() fails.

In Android's Media Framework, libminijail (which I believe is a sandbox)
aborts the process if pthread_getschedparam() is called:

  media.swcodec: libminijail[7526]: blocked syscall: sched_getparam
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  /system/bin/tombstoned: received crash request for pid 7526

Although this CL cannot handle that extreme failure mode, it handles an
error return from pthread_getschedparam() and won't use the uninitialized
param.sched_priority value in that case.
